Quick Answer
Glass aquariums resist scratching, remain optically stable, and are widely available, while acrylic aquariums are lighter, more impact resistant, and easier to shape in large or custom designs. Choose glass for routine household tanks and easier surface care; choose acrylic when weight, shape, or very large size matters and scratch prevention is manageable.
